APsystems RSD-S-PLC Single PV Module Rapid Shutdown Device (415002)

Module-Level Rapid Shutdown Protection for Solar PV Systems

The APsystems RSD-S-PLC (415002) is a high-performance, single-module rapid shutdown device (RSD) designed to meet NEC 2017, 2020, and 2023 (690.12) safety requirements. Powered by SunSpec-compliant Power Line Communication (PLC), the RSD-S-PLC seamlessly integrates with string inverters and transmitters to ensure maximum safety for solar installers and emergency first responders.

Designed to control 1 individual PV module, the RSD-S-PLC is ideal for odd-numbered module counts, irregular roof layouts, or installations requiring precise individual-module control.

Key Features & Benefits

• Single-Module Control: Attaches directly to a single PV module, providing flexible array design and precise safety control for residential and commercial systems.

• SunSpec PLC Communication: Uses standard SunSpec Power Line Communication (PLC) over DC lines, eliminating the need for additional signal wiring or wireless network setup.

• NEC 690.12 Compliance: Attenuates array voltage below 30V within 30 seconds of system shutdown, ensuring full compliance with national safety standards.

• Automatic Safety Shutdown: Automatically executes rapid shutdown when the AC utility power is cut or when the PLC transmitter signal is interrupted.

• Weatherproof & Rugged: Features an IP68 / NEMA 4X enclosure engineered to endure harsh rooftop weather conditions and extreme temperatures.
